Washington (CNN) Special counsel Robert Mueller sought information directly last year from one of Donald Trump's campaign pollsters who is also a former business associate of Paul Manafort's. A source familiar with the special counsel's interest said Fabrizio's interview included questions about his polling work for Manafort in Ukraine rather than his internal Trump campaign polling. The Justice Department initially asked Mueller to look into Manafort's political ties in Ukraine because they may relate to other allegations of Russian coordination with the Trump campaign. His relationship with Trump soured late in the election as the Trump campaign disputed a bill of roughly $767,000 to Fabrizio's polling firm. The two men also discussed a Ukrainian peace plan while Manafort was serving as Trump's campaign chairman.
